Abstract

An image processing apparatus includes: an image display control unit controlling an image display on a display screen; an image generating unit generating a question image including a question and option buttons configured by icons that can be arbitrarily selected for the question; a position detecting unit detecting a position of a pointer present on the display screen from imaging data acquired by imaging the display screen; a position information storing unit storing positions of the icons when the question image is displayed on the display screen; and a control unit specifying an icon out of the icons selected by the pointer based on the position of the pointer and calibrating the position of the pointer based on the position of the icon, which is stored in the position information storing unit, corresponding to the icon specified to have been selected.

Claims

1. An image processing apparatus comprising:

an image display control unit that controls an image display on a display screen;

an image generating unit that generates a question image including a question and option buttons configured by a plurality of icons that can be arbitrarily selected for the question;

a position detecting unit that detects a position of a pointer that is present on the display screen from imaging data acquired by imaging the display screen;

a position information storing unit that stores positions of the plurality of icons when the question image generated by the image generating unit is displayed on the display screen; and

a control unit that specifies an icon out of the plurality of icons that is selected by the pointer based on the position of the pointer detected by the position detecting unit and calibrates the position of the pointer that is detected by the position detecting unit based on the position of the icon, which is stored in the position information storing unit, corresponding to the icon specified to have been selected.

2. The image processing apparatus according to claim 1, wherein the question is a question that is different from a question that is exclusively used for calibration.

3. The image processing apparatus according to claim 2, wherein the control unit performs a setting process corresponding to the question and the icon specified to have been selected and performs the calibration process in parallel with the setting process.

4. The image processing apparatus according to claim 2, wherein the control unit acquires screen size information of the display screen and allows the image generating unit to change sizes of the option buttons in accordance with the screen size information.

5. The image processing apparatus according to claim 1, further comprising:

an acceleration sensor; and

an angle sensor,

wherein, in a case where a mounting position of the image processing apparatus is detected to be deviated from a reference position of the display screen based on outputs of the acceleration sensor and the angle sensor, the control unit allows the image generating unit to generate the question image and displays the question image on the display screen.

6. The image processing apparatus according to claim 1, further comprising at least one imaging unit that images the display screen.

7. A method of displaying an image, the method comprising the steps of:

generating a question image including a question and option buttons configured by a plurality of icons that can be arbitrarily selected for the question by using an image generating unit included in an image processing apparatus;

detecting a position of a pointer that is present on the display screen from imaging data acquired by imaging the display screen on which an image display is controlled by an image display control unit included in the image processing apparatus by using a position detecting unit that is included in the image processing apparatus;

specifying an icon out of the plurality of icons that is selected by the pointer based on the position of the pointer that is detected by the position detecting unit by using a control unit included in the image processing apparatus; and

calibrating the position of the pointer, which corresponds to the icon specified to have been selected, detected by the position detecting unit based on the position of the icon when the question image, which is stored in a position information storing unit included in the image processing apparatus, generated by the image generating unit is displayed on the display screen.

8. An image display program that allows a computer to function as:

an image display control means for controlling an image display on a display screen;

an image generating means for generating a question image including a question and option buttons configured by a plurality of icons that can be arbitrarily selected for the question;

a position detecting means for detecting a position of a pointer that is present on the display screen from imaging data acquired by imaging the display screen;

a position information storing means for storing positions of the plurality of icons when the question image generated by the image generating means is displayed on the display screen; and

a control means for specifying an icon out of the plurality of icons that is selected by the pointer based on the position of the pointer detected by the position detecting means and calibrating the position of the pointer that is detected by the position detecting means based on the position of the icon, which is stored in the position information storing means, corresponding to the icon specified to have been selected.

9. A recording medium on which the image display program according to claim 8 is recorded.
